Abstract (en)
[origin: EP3760652A1] The present invention provides an ethylene/alpha-olefin copolymer which has: a low density and ultralow molecular weights with a narrow distribution of molecular weights; a minimum number of unsaturated functional groups; and comonomers uniformly existing thereacross, thereby exhibiting excellent physical properties, and a preparation method therefor.
